AI Technical Summary

Problems solved by technology

[0003] The common faults of rotating machinery are vibration faults. Vibration faults include unbalance, misalignment, bearing damage, resonance, etc. Excessive vibration will cause damage to rotating machinery, and even require shutdown for maintenance. This will not only cause serious economic losses, but also bring adverse social impact

Abstract

The invention discloses a rotation mechanical vibration fault simulation system. The simulation system is internally provided with a motor controller, a motor and multiple rotation machines in an integrated mode, and by adjusting the input torque and the rotating speed of the motor through the motor controller, vibration fault simulation under different working conditions can be realized. In such a way, when it is monitored that abnormities occur in the actually running rotation machines, the faults occurring in the rotation machines can be simulated through the simulation system, and then data needed for diagnosing the vibration faults is extracted on the simulation system and correlation experiment research is carried out, such that the influences caused by long-time closure of the rotation machines to production in the prior art are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical mechanics, in particular to a vibration fault simulation system for rotating machinery. Background technique [0002] Rotating machinery refers to the machinery that mainly relies on rotating movements to complete specific functions. It is a kind of machinery that is widely used in industry. Typical rotating machines include gas turbines, centrifugal and axial compressors, fans, pumps, water turbines, generators, and aeroengines. Rotating machinery is widely used in petrochemical, electric power, metallurgy, coal and other industries. [0003] The common faults of rotating machinery are vibration faults. Vibration faults include unbalance, misalignment, bearing damage, resonance, etc. Excessive vibration will cause damage to rotating machinery, and even require shutdown for maintenance. This will not only cause serious economic losses, but also bring to negative social impact. [0004] At pr...
